The blockchain and cryptocurrency world has witnessed an innovation explosion in recent years, giving rise to many blockchain platforms, each with unique features and capabilities. Among the most prominent players in this space, we will compare Ethereum vs Cosmos.
These two platforms have garnered significant attention and are often hailed as the pioneers of decentralized technology. But when it comes to choosing the superior option, the question arises: Ethereum or Cosmos? Which one is better suited to meet the demands of the expanding blockchain landscape?
What is Cosmos?
The Cosmos blockchain was created to make it easier for distributed ledgers to communicate with each other, all without relying on a central server. 2016, the Cosmos white paper was published, and its founders saw it as the “Internet of blockchains.” They aimed to build a platform where different open-source blockchains could work seamlessly to improve transactions. Since blockchain technology began, making different systems communicate has been challenging for developers.
Interoperability is the key to enabling communication between two or more systems. Think of it as emails from a Gmail account reaching a Hotmail account or an Android phone sharing data with an Apple iOS device. At first, systems like specific blockchains are created independently. But to be truly useful, they need to talk to each other. Otherwise, they can become a roadblock to technological progress.
Cosmos is a groundbreaking platform that provides free interoperability between various systems, including Binance Chain, Crypto.org, and more. It manages billions of dollars worth of digital assets. The cryptocurrency that powers and secures this ecosystem of interconnected blockchains is called Cosmos (ATOM). It is crucial in enabling these blockchains to scale and work together seamlessly.
How Does Cosmos Work?
The Cosmos network is a continuously growing ecosystem of interconnected apps and services. It achieves secure communication between blockchains through hubs, the Tendermint consensus algorithm, and the Inter-Blockchain Communication (IBC) protocol. Some platforms rely on smart contracts to communicate with each other. In this process, tokens are locked on one platform, and an equivalent asset is generated on the receiving platform. Wrapped tokens exemplify this.
Instead of directly sending Bitcoin (BTC) from the Bitcoin blockchain to another platform like Ethereum, Cosmos takes a different approach. BTC is locked within a functional blockchain that offers the desired service, and a corresponding amount of tokens (e.g., wrapped Bitcoin or wBTC) is issued on the target blockchain.
In contrast to a single blockchain, Cosmos provides open-source tools that empower developers to create decentralized and autonomous blockchain applications called “zones.” These zones function as Cosmos smart contracts. The Cosmos team has developed a software development kit (SDK) that enables developers to build zones faster, more easily, and cheaper than other platforms like Ethereum. It simplifies things by offering commonly used blockchain functionalities such as staking, governance, and tokens through user-friendly software development tools like GO. Developers have the freedom and flexibility to add plugins and incorporate any needed features.
What is Ethereum
Ethereum is a decentralized blockchain network that runs on its native digital currency called Ether (ETH). This platform offers various functionalities, such as facilitating transactions, allowing users to earn rewards by staking their Ether, supporting the creation and trading of nonfungible tokens (NFTs), enabling cryptocurrency trading, hosting games, providing a platform for social media, and much more.
In many ways, Ethereum is the next evolution of the internet. While centralized platforms like Apple’s App Store represent what’s known as Web 2.0, Ethereum embodies the concept of Web 3.0, which is a decentralized and user-driven network. Web 3.0 supports decentralized applications (DApps), decentralized finance (DeFi) platforms, and decentralized exchanges (DEXs), among other things.
How Does Ethereum Work?
Ethereum functions as a decentralized blockchain platform. Nodes, interconnected computers, maintain the network, ensuring transaction transparency and security.
Ethereum’s hallmark feature is its support for smart contracts. These self-executing code agreements remove intermediaries, operating autonomously when conditions are met. Ethereum users employ its native cryptocurrency, Ether (ETH), for transactions and gas fees. Ether serves various roles, compensating validators in Ethereum 2.0 for transaction processing and incentivizing network security.
A typical Ethereum transaction involves initiation, broadcasting, and confirmation. Users initiate transactions, such as Ether transfers or smart contract interactions. Broadcasted transactions are picked up by nodes. Validators under Ethereum 2.0 compete to incorporate transactions into blocks. Successful additions result in immutable blockchain records. The amount of gas fees prioritize and process transactions.
Ethereum’s adaptability, smart contract capabilities, and the transition to energy-efficient consensus mechanisms have made it a blockchain cornerstone. It fosters decentralized finance (DeFi) platforms, non-fungible tokens (NFTs), and decentralized applications (DApps), cementing its role as a pivotal blockchain and cryptocurrency player.
Differences between Ethereum and Cosmos
Design Philosophy and Purpose
Ethereum: Ethereum’s primary goal is to create a decentralized platform for building decentralized applications and smart contracts. It aims to be a global, open-source, and trustless computer that supports various use cases, from DeFi to NFTs.
Cosmos: Cosmos is designed with a focus on interoperability and scalability. It aims to create an interconnected network of blockchains, known as the Cosmos Hub, and various zones, allowing different blockchains to communicate and share data securely.
Ethereum: Ethereum currently operates on a proof-of-stake (PoS) system which improves scalability and energy efficiency.
Cosmos: Cosmos uses a consensus mechanism called Tendermint, a PoS-based Byzantine Fault Tolerant (BFT) consensus algorithm. Tendermint is designed for speed and security and is used across the Cosmos ecosystem.
Ethereum: Ethereum’s approach to interoperability has evolved with Ethereum 2.0 and efforts like the Ethereum Beacon Chain. It improves scalability and facilitates communication between Ethereum and other blockchains through technologies like shard chains.
Cosmos: Interoperability is a central focus of Cosmos. It uses the Inter-Blockchain Communication (IBC) protocol to enable various blockchains within the Cosmos ecosystem and even external blockchains to connect, share data, and transfer assets seamlessly.
Ethereum: Ethereum is primarily a single blockchain network hosting many DApps and DeFi projects on its mainnet.
Cosmos: Cosmos adopts a hub-and-zone architecture. The Cosmos Hub is the central chain, while different zones (independent blockchains) can connect. Each zone can have its unique consensus mechanism and application, enabling diverse use cases and experimentation.
Native Tokens and Governance
Ethereum: Ethereum’s native cryptocurrency is Ether (ETH), used for transaction fees, smart contract execution, and staking. Ethereum also has plans to implement Ethereum Improvement Proposals (EIPs) for on-chain governance.
Cosmos: Cosmos’ native token is Atom (ATOM), used for staking, network security, and governance. Cosmos relies on a proposal and voting system for network upgrades and changes.
The Blockchain Trilemma Explained
The concept of the blockchain trilemma revolves around the idea that blockchains face a crucial choice between three essential attributes: decentralization, scalability, and security. However, it’s like a “pick two out of three” scenario because achieving all three simultaneously is incredibly challenging.
For Ethereum, it has historically prioritized decentralization and security, which meant that scalability had to take a back seat. This trade-off has posed challenges for Ethereum’s network performance.
On the other hand, Cosmos has taken a different approach. Cosmos aims to tackle the trilemma more effectively by adopting a modular framework. This approach allows Cosmos to offer scalability alongside decentralization and security, potentially providing a well-rounded solution to the blockchain trilemma.
Similarities between Ethereum and Cosmos
Ethereum and Cosmos are both prominent blockchain platforms, and while they have distinct features and goals, they share some fundamental similarities:
Ethereum and Cosmos are built on the principle of decentralization. They rely on a network of nodes (computers) distributed worldwide to validate and secure transactions. This decentralization enhances security, resiliency, and censorship resistance.
Smart Contract Support
Ethereum and Cosmos both support smart contracts, which are self-executing contracts with the terms of the agreement directly written into code. Smart contracts enable the creation of decentralized applications (DApps) that can automate various processes without intermediaries.
While they approach it differently, both platforms prioritize interoperability. The Ethereum 2.0 upgrade improved scalability and interoperability with other blockchains. On the other hand, interoperability is a core focus of Cosmos, which aims to create a network of interconnected blockchains that can communicate seamlessly.
